Abstract

A battery checker is provided with: voltage application unit configured to apply an AC voltage to a battery to be measured; ripple voltage measurement unit configured to measure a ripple voltage contained in a terminal voltage of the battery; and electric power storage level detection unit configured to detect an electric power storage level of the battery by comparing the measured ripple voltage with a set reference. The voltage application unit includes a transformer that transforms voltage for an alternating current of an AC power supply such as a commercial AC power supply, and an output circuit that applies, to the battery, an alternating current with transformed voltage.
